Problems solved by technology
[0002] Usually, the demoulding device of the small and medium-sized dry powder press (referring to the dry powder press below 150T) adopts a double-sided cam and a pressure bar demoulding structure to realize the demoulding after the product is pressed and formed. The double-sided cams of the demoulding device are fixed at both ends of the main shaft. The fixed angle of the two cams and the external curve of the cam are completely guaranteed by the processing accuracy, and it is easy to have inconsistencies in processing, and once inconsistencies occur, it is difficult to modify
During use, the fixed angle of the cam and the external curve of the cam are difficult to ensure consistency. The cam drives the demoulding rod to move downward through the roller mounted on the demoulding rod to drive the lower beam to demould. The inconsistency of the curves makes the movement of the ejector lever asynchronous, causing the lower beam to tilt, which affects the accuracy of the machine's ejection movement, thus affecting the quality of the pressed product

The invention relates to a unilateral stripper apparatus of a medium and small size dry powder press and is applicable to the medium and small size dry powder press for stripping products after forming. The structure comprises a cam, idler wheels, a stripping lever, a stripping arm, a stripping axle, a stripping pry bar and a stripping compact. The cam is equipped at the principal axis end of the dry powder press; the stripping lever is equipped on a support of the stripping lever; the support of the stripping lever is equipped at a housing side of the dry powder press. The idler wheels are equipped at top of the stripping lever and contact the cam. A lower idler wheel is equipped at bottom of the stripping lever or one end of the stripping arm which is equipped at one end of the stripping axle. The stripping axle is equipped on the housing of the dry powder press. The stripping pry bar is equipped on the other end of the stripping axle. The stripping compact is equipped on the stripping pry bar and pressed under the lower beam.
